UNITED STATES PATENT OFFICE.

ROBERT POWERS, OF CHARLESTON, MISSISSIPPI.

Specification forming part of Letters Patent No. 135,486, dated February4, 1873.

To all whom it may concern:

Be it known that I, ROBERT Pownns, of Charleston, in the county ofTallahatchee and State of Mississippi, have invented a new and ImprovedCotton-Press, of which the following is a specification:

This invention consists of the hereinafterdescribed arrangement ofapparatus for working the screw of a screw cotton-press, both forpressing the cotton and withdrawing thefollower.

Figure 1 is partly a side elevation and'partly a sectional elevation ofmy improved press. Fig. 2 is a plan view, and Fig.3 is a transversesectional elevation.

Similar letters of reference indicate corre spondin g parts.

A is the follower; B, the screw for working it. C is a large revolvingnut, through the center of which the screw works, the said nut beingconfined between the cross-bars D in the top of the vertical press-frameE, so as to rise and fall by the turning of the nut, which is effectedby a belt worked by a small pulley, G, on a counter-shaft, H, one end ofwhich runs against the end of another shaft, I, which may be theordinary band-wheel shaft of a horse-power for driving a cotton-gin, andis to be provided with a clutch of any approved kind by which it can bereadily connected to said shaft to be turned by it, or disconnected; andthe two shafts have each a bevel-pinion, K, near the ends, facing eachother, with which there is another pinion, L, arranged in such manner onan adjustable support, M, that it may be readily brought into gear withthem, when the aforesaid clutch is disconnected, to reverse the motionof the nut O, and raise the follower, after it has been forced down topress the bale, by the direct action of the drivingshaft I on thecounter-shaft, through the medium of the aforesaid clutches.

Having thus described my invention, I claim as new and desire to secureby Letters Patent--' The combination, with the revolving nut O andpress-screw B, of the counter-shaft H, driving-shaft I, pinions K, andthe adjustable pinion L, substantially as specified.

ROBERT POWERS.
